Psychodermatology of acne: Psychological aspects and effects of acne vulgaris

INTRODUCTION

Acne is a chronic inflammatory skin condition seen commonly in adolescence and young adulthood. Despite being a frequent and nonthreatening life condition, acne has a significant psychological impact and comorbidity.

AIMS

This review will describe prevalence, common clinical features, different clinical presentations, differential diagnoses, and treatment recommendation. Special focus has been put on psychological aspects.

METHODS

We conducted a literature search on PubMed from January 2001 to June 2020 with the search terms of Acne vulgaris, psychological, adolescents, anxiety, suicide, mood disorders. Reference lists of identified articles were examined for further relevant studies. The search was limited to English language articles. No specified quality criteria were used for study inclusion.

RESULTS

The clinical manifestations of acne are very important in the differential diagnosis and its psychological implications.

CONCLUSION

Through this article, we conclude that despite being a frequent and nonthreatening life condition, acne has a significant psychological impact which requires effective treatment to improve the patient's skin and self-esteem.

Lupus miliaris disseminatum faciei in a patient with systemic lupus erythematosus and Sjögren's syndrome

We herein report a rare case of lupus miliaris disseminatus faciei on the chin and neck in a patient with systemic lupus erythematosus and Sjögren's syndrome. Histopathological features showed focal aggregates of epithelioid granulomas accompanied by mononuclear cell infiltration in the upper dermis. Immunohistological examination showed enhanced expression of CD68 and CD163. Recent findings have implicated a key role of innate immunity in the pathogenesis of systemic lupus erythematosus, and alteration in M1 and M2 macrophage profile has been suggested. Increased expression of CD163 in the affected skin and other organs, and elevated serum levels of soluble CD163, are reported in systemic lupus erythematosus. Our results may suggest that activated M2 macrophages participated in the induction of lupus miliaris disseminatus faciei in a patient with systemic lupus erythematosus and Sjögren's syndrome.

Case for diagnosis. Eyelid edema and erythematous papules disseminated on the face

Lupus miliaris disseminatus faciei or acne agminata is a chronic inflammatory disorder of the skin, considered an intriguing entity due to its pathogenesis, which is still largely speculative. It has been linked to tuberculosis, sarcoidosis, rosacea, and other granulomatous diseases, but it is considered an independent entity.

Lupus miliaris disseminatus faciei: a distinctive facial granulomatous eruption

Facial granulomatous papules are important to recognise, as some of them are associated with significant systemic association, particularly sarcoidosis and certain infectious conditions. Lupus miliaris disseminatus faciei (LMDF) is a benign granulomatous disorder of unknown aetiology characterised by symmetrical, monomorphic, reddish-brown papules on the face. It is not associated with any underlying systemic involvement. We report a case of LMDF in a middle-aged man who presented to us with multiple asymptomatic and monomorphic reddish papules on the face for 3 months. Skin biopsy showed well-formed perifollicular epithelioid cell granulomas with focus of necrosis suggestive of LMDF. The lesions significantly responded to oral steroids.
